TIE Institute of Technology, at Boston,
long ago decided upon the danger OF
steam pipes passing through and in con-
tact with wood. 1t was shown that the
wood, by being constantly heated, as
sumes the condition, TO a greater or less
degree, OF fine charcoal. a condition high
ly favorable to spontaneous combustion.
A LATE observer, Mr.. f. Sandiord, re-
ports having made a common snail carry
a load OF two and a quarter ounces up a
perpendicular wall, its own weight being
about a quarter OF an ounce. A snail
weighing 4 third OF an ounce drew a load
OF seventeen ounces on horizontal table,
and supported four ounces while crawl
ing on the ceiling. 1t even climbed 4
thread with another snail on its back.
To cut glass tubes hv electricity. an
iron wire one half minim in diameter is
wound around the tube at the place
required TO be cut, and the ends are con-
nected by means OF copper conductors of
the same diameter with the poles of
powerful battery. This iron becomes
heated when the current flows, and il is
only necessary to cool it suddenly with
few drops OF cold water in order to pro-
cure clear cut. Glass tubes four inches
IN diameter are now cut III this way
VIZ have met with the following cheap
mode for painting out door structures:
Make four gallons of paste of rye flour,
like the paste used for papcring rooms,
and then mix in one gallon OF common
OF. paint. This will cover as much sur
face as five gallons OF paint alone, For
the second coat add two gallons of oil;
and three for the third. These three
coats will last about as longas three coats
OF oil paint. A good paint for brick is
made OF fresh lime wash and sulphate of
link.
IvoRY scales, padcr knives and 30 on,
may be cleaned by scrubbng them with
4 new soft tooth brush, soap and tepid
water; then dry the ivory and brush
well, dip the latter III alcohol and polish
the ivory until it has rcgaincd its former
sheen. II the water gives the ivory q
yellowish tint dry the object in heated
place. Ii age has ycllowcd it place the
object under a bell jar with vessel con-
tanning lime and muriatIc acid, and set
the whole in the sunshine.
SIR Joseph WhitwOrth was the first to
inaugurate a system of Standard screw
threads. The form of thread, and the
number of threads per inch which he
recommended, were based partly on the
results OF numerous experiments and
partly on the average obtained by COM
pairing the various forms Of screwed bolts
then in use. The Whitworth system has
been very generally adopted in all parts
OF the civilized world except the United
States. The Seller system introduced
here III 1864 has the same number of
threads per inch, but the form of the
thread is different.
WIRES and bars are now produced dir
ect from fluid steel by pressing it through
dies in a manner similar to the produc-
ton of lead pipes from lead An iron
J.
provided with 4 man hole, and cover at
the top and securely closed. At the bot
tom, opposite the man hole, there is cast
IRON outlet pipe, through which passes a
steel tube with water circulating around
it like "tUyere,' by which the steel pipe
or die can be cooled. The inner end OF
the steel tube is lined with fire clay,
where the very hot fluid steel meets it.
The tube is plugged up by steel stop
per, and the liquid steel is filed into the
vessel with liquid carbon dioxide above
it. The stopper being withdrawn. liquid
steel is forced out, by pressure Of the car
bon dloxide, in n red hot rod or wire,
which goes from the vessel into the roll
ling mill while still hot, and is there fin
ished off.
THE Bayeux tapestry IS almost a uu-
ique piece OF unwritten history Des-
cription OF it have been more than once
attempted but perhaps the analysis of
1t worth most is one recently issued at
Copenhagen. Prof. Johannes Steenstrup
is the writer. His little book gives an
explanation of fifty latin inscriptions
found on the tapestry, and OF a series OF
figures sewn into it with eight different
colors Herr Stceustrup states of the
1912 figures which comprise the picture
story OF the conquest of England, that
623 represent persons, POP horses, sos
other animals, 81 buildings, ships, and
boats and 40 trees. The tapestry is pa
feet long. Further, he has arrived at the
conclusion that Bishop Odo, of Bayeux,
caused the tapestry to be made in COM
mcmoration Of the expedition in which
he himself took part. doubtless he says,
the figures were made by Normans, and
the fingers of Norman women piled the
needles. The taspestry was made 10

WHICH Was dedicated at PayeuX IA IQ7L.<
